which part is the (false) antecedent, and which part is the statement?
If you’re looking for a never true anticedent reason that “some content and ads you see may not be as relevant to you” is vacuous, that would work if they had an ad browser that was 100% effective on the site in question.
If you’re looking for a never true anticedent for “If trackers are disabled, some content and ads you see may not be as relevant to you.”, it’s that you can’t disable all trackers with a cookie dialog because of the “necessary cookies” blanket exemption, the too many tick boxes to use “legitimate interest” loophole, and that most websites use “fingerprinting”, meaning they reference you not by your cookies but by the worryingly extensive information they get automatically about your browser’s version, settings, capabilities and features, and of course IP address. So it’s never true that trackers are never disabled.
What the Wikipedia article doesn’t explain well in my view, is that logically, “if A then B” means “B or not A” for short, or more explicitly, “in all circumstances, at least one of B, or (not A) , is true”. This is vacuously (emptily) true if B is always true or A is always false, because it’s not genuinely conditional at all.
So I suspect that they meant it was vacuous, not on the grounds that the anticedent could never be true, but that the consequent could never be false. Like “If you give me $10, the sun will rise tomorrow”. In this case, all they need to assert is that “some content and ads you see may not be as relevant to you” is true irrespective of whether trackers are disabled, which is almost certainly what they meant.
I’m curious that the Wikipedia article says the base case in an induction is often vacuously true, but I think they mean trivially true, like cos(1x) + sin(1x) = (cos x + sin x)^1, not vacuously true. I couldn’t think of any induction proofs where the base case was literally vacuous except false ones used for teaching purposes, probably because I could only think of induction proofs of absolute rather than conditional ones. Probably there are mathematical fields where induction is used for conditional statements a lot that I’m forgetting.
